We just put this graph here to be suspensefulh, the Alpha heatsink really does kick ass, and you'll see that for yourself in a few moments.

Currently, in this list of reference heatsinks the Alpha PAL8942 offers the best performance on the socket 478 platform. The AVC sunflower and the all copper twin heatpipe bearing Coolermaster IHC-H71 round out the top three positions. In general we have seen some really good things coming out of Alpha lately, and while there is always room for improvement, the PAL8942 offers a lot to the average user, or the performance user in terms of quality.

We also tested this heatsink with a 38mm Delta and the results were even better with the PAL8942 averaging a rise above ambient temperature under the 100W test load of just 22.8 degrees Celsius! Those results were with the jumbo 38mm thick Delta fan in the exhaust orientation, and for comparisons sake, with that same fan in an impingement orientation the heatsink performed to the tune of 24.5 degrees rise above ambient (not quite as efficient).

There isn't really much to say, the performance numbers for the Alpha PAL8942 are great with the standard 25mm thick stock fan, and even better with a high performance (and incredibly noisy) 38mm thick Delta.
